Among ceramics filter support materials, such as titanium alumina, mullite, zirconia, spodumene, and cordierite, cordierite is known as a good candidate material due to its high thermal shock resistance and low thermal expansion coefficient [2, 3].

Introduction During earthquake attack some structures severely damaged and collapse completely but some damaged to certain degree and become highly susceptible for future attack[5].The major cause of catastrophic collapse is due to lack of proper repairing of past earthquake damaged members of the structure.Effective repairing technique is necessary to restore the strength and make resistant enough if any earthquake occur in the future[4].Sprayed FRP composite is one of the emerging solutions in this regard[6].Due to high row material abundance and low production cost, basalt fiber can be considered as the best alternative fiber material for strengthening of structures.Basalt fiber not only own high-strength, high-elastic modulus and impact resistance that can be on a par with high-tech fibers, but also has good thermal shock resistance, corrosion resistance, fiber proof, better interface bonding strength combining with resin[1].
The material properties of the basalt fiber and the resin used for this test program are shown in Table.2, and Table.3.The basalt fiber was BC13-1200 chopper roving, manufactured by Sichuan Aerospace Tuoxin Basalt Industrial Co., Ltd.

Physical and mechanical parameters of soil body and fracture surface used in the finite difference analytical model are selected based on the conventional range of the geo-materials after comprehensive consideration, as shown in Table 1.
Conclusions (1) Stretching deformation of the basin basement makes the state of horizontal compressive stress in the superficial geo-materials changed gradually from compressive stress to tensile stress, so as to form the regional tectonic stress field in favor of the formation of ground fissure; (2) Stretching deformation of the basement gives rise to the normal dip-slip motion of main fault, and additional stretching deformation is formed in the rock-soil body within a certain range of fault zone of hanging side, more conducive to the formation and development of ground fissure in the rock-soil body.
